The Agilent 81623A optical head is designed for low PDL, low spectral ripple, and high return loss for optical component testing. The optical head must be operated with a single (Agilent 81618A) or dual (Agilent 81619A) interface module. The heads come with a magnetic D-shaped adapter and are provided with a safety mount. They are used in the Lightwave host models 8163A/B, 8164A/B, and 8166A/B.

The 81623A is the predecessor to the 81623B. The following is Agilent's description of the differences between the two models.

What is the difference between the 8162xA and 8162xB optical heads?

Much of the functionality of the 8152x optical head was retained when Agilent Technologies first introduced the 8162xA series of optical heads. However, the 8162xA optical head did not have an available analog output. 8162xB models, with the exception of the 81625B (now replaced by the 81626B), offer an analog output on the optical head.

In addition, a number of specifications have been added. For example, the 81623B now has a specification that varies with polarization power. 81623A does not.

The main difference is that the 8162xB models (except the 81625B) offer analog outputs, while the 8162xA does not. All of the features offered by the 8162xA are available on the corresponding B models.
